Abstract

This paper describes the concept and basic principles of methods for determining the regions of functional neuronal connectivity of the human brain which formed the basis of the Neuroimaging system at the National Research Center “Kurchatov Institute” for processing and analyzing experimental MRI/fMRI data. A method of functional segmentation (MFS) module of the system is presented for remotely launching tasks of identifying functionally homogeneous regions of the human brain at rest by using a unique MFS method that provides clustering using Pearson’s correlation coefficient. Tests of the module on real fMRI data is described.

使用功能核磁共振成像 (fMRI) 数据计算人脑休息和神经成像区域的功能连通性的实施方法

摘要

本文描述了确定人脑功能性神经元连接区域的方法的概念和基本原理,这些方法构成了国家研究中心“库尔恰托夫研究所”神经影像系统的基础,用于处理和分析实验 MRI/fMRI 数据。提出了一种系统的功能分割 (MFS) 模块方法,用于通过使用独特的 MFS 方法远程启动识别人脑静止功能同质区域的任务,该方法使用 Pearson 相关系数提供聚类。描述了该模块在真实 fMRI 数据上的测试。
